Well its 1 of 2 things either the winding is bad in which case you'd smell a sicky burning chemical smell, or the bearings have seized. I'm guessing the winding is bad. If its a cheap Walmart bought fan then just replace it, if not you can take it apart yourself pretty easily. You may have trouble getting the bearings of the shaft, i use a die grinder with a cutoff wheel on it, just try not to cut into the shaft, you can crack it with a hammer after your almost through then they usually just slide off. Then swing up to a bearing store they'll probably just be a couple of bucks a piece(tell them you don't care what class they are just gimme the cheapest except dolly bearings, and bring the old ones with you). Then get a piece of pipe that matches the "inner race", and carefully hammer them onto the same part of the shaft(mark it prior if there is no bearing shoulder), if there are copper wires running through the laminations (if there are any) on the shaft, tape a rag around them to prevent damage. If any of the wires are damaged on the inside of the motor go buy a new one, it'll cost several hundred to rewind it.

LG lp 1010snr portable ac compressor will not start

Its hard to say with out some more information like what is the HP of the motor and what is the cubic ft per minute SCMF RATING and what size is the air tank. And is the compressure a single pistion dry lub or larger oil filler unit . Off the top of my head if it humes your getting power to the pump . If the tank has on air pressure in it . I would look for a binding problem see if the fan will spin freely . If it has a belt remove it and see if the pump and the motor spin freely . It sounds like a mechinacil problem as apposed to electrical

Hello i have a international harvester model 100 diesel portable torpedo haeter. my problem is that when i plug it in i get a humming noise and it doesnt start. can u please help????

Sounds like the fan/fuel pump motor is not turning so try this. Take the top section of the heater tube off, this exposes all of the internal working parts. Now locate the fan motor and fan, try turning the fan by hand, should spin nice and easy if not take a light oil or I like PB Buster and oil bearings on the shaft behind the fan, then first set in the front of the motor, then the bearings at the rear of the motor. You do this and spin the fan by hand as many times as it takes for that fan to spin freely. Then plug it in and try to fire it off, if it worked shut it off put it back together and happy heating. If not you may need a new fan motor or could be something in your fuel pump, usually it will be motor related .

1994 XJ 40 Sovereign Do the 2 electric fans start up together in tandem, or do they have seperate feeds and possibly start up at different times, I ask because the bottom fan I have never seen actually...

normally one comes on when you power up the airconditioning, but at some point they should both work, when the car has stood stiil with engine running in warm weather, if you can get a test lamp and check for power to the motor when rad hot, or join the two wires from the temp switch on the rad or rad hoses this should power the fan , while ign off and motor cold spin fan incase its siezed and blown fuse

Heater won't start

Thanks for your question,
Sounds to me like you have a faulty fan in the unit, could be stuck, or might be a bad fan motor, try unplugging it first, find something to insert where the fan is and try spinning the blade, if its stuck or has alot of resistance, then you have a bad motor, if its free spinning, then try plugging it back in and see if it works, sometimes just by manually moving the motor shaft it frees it to work, if it still doesnt work, then you might look at replacing the fan motor, or replacing the unit, hope this helps ya,

Pc Seems to be dead wont load bios post moust doesnt work or keyboard or monitor

I have the same problem, the CPU fan spins, keyboard lights blink, no start up screen, or bios.
But, when I push a few times on the pc reset button, then the CPU fan is becoming still, the keyboard light are out and I can start the computer again in a normal way.
Can this one be a temporally solution for you too? Do you have any suggestion about?
I guess it can be an electricity dysfunction of a wrong fixed cable.

Computer doesnt start

It sounds like your struggles may have damaged the motherboard. See other issues in this forum with this motherboard - partcularly with bowing of the board. Too much bowing can cause internal traces in the PCB to break. Only way to tell now is have it professionally looked at.
